WIN10 microsoft store 預覽主題時，整個store無回應，只能縮小但無法再次打開

Hi! It's strange that it only happens with the themes. It's very specific. But you can try repairing the store.

Run the troubleshooter

1. Open Windows Settings (press CTRL+I) > Select "Update & Security" > In the left panel, select "Troubleshooting".
2. Select "Additional troubleshooting" > Select "Windows Store apps" > Run troubleshooting.
3. Restart the computer.

Restore Store

1. Open Windows Settings (press CTRL+I keys) > Select "Applications " > In the left pane, select "Applications and features".
2. Search for "Microsoft Store" > Select and click "Advanced options".
3. First, click "Finish"" > Under "Reset", click "Repair" > Then click "Restore" > Restart the computer.
4. See if the problem has been solved.

Restart Services

1. Type "'PowerShell" in the Search Bar > Right-click on the app > Select ''Run as administrator''.
2. Now, enter the following commands.

ATTENTION: Type or copy the entire command in the first line > Press ENTER > Wait for the command to complete.

net stop bits

net stop wuauserv

net stop appidsvc

net stop cryptsvc

Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"

rmdir %systemroot%\SoftwareDistribution /S /Q

rmdir %systemroot%\system32\catroot2 /S /Q

regsvr32.exe /s atl.dll

regsvr32.exe /s urlmon.dll

regsvr32.exe /s mshtml.dll

netsh winsock reset

netsh winsock reset proxy

net start bits

net start wuauserv

net start appidsvc

3. Restart the computer when finished > Check if the problem will be resolved.

Something that might help is signing out of your Microsoft account in the store (User icon > Sign out) > Restart your computer > Sign in again.
